Obsessive-Compulsive Symptoms (OCS) are characterized by repetitive thoughts and behaviors. People with regularly debilitating OCS may be tested for OCD (Obsessive-Compulsive Disorder). However, OCD is not a binary condition and exists more as a spectrum. In this project, my partners and I looked at the heterogeneity of OCS domains by analyzing the associations of neurocognitive variables with the 5 domains and used the OCS inventory to predict depression.
